This is a calculated estimate derived from the figures you entered and the factors in the configuration layer. It is not a measurement of your emissions.

Current vs. renewable scenario
EstimateCompares your current modelled emissions with the same footprint after the 5.0 kW solar array selected below displaces grid electricity. Only electricity emissions can be displaced by solar generation.

Solar Potential
EstimateA first-order screening estimate of what a rooftop or ground-mount solar array could generate, and the grid electricity emissions it could displace. Adjust any parameter to see the effect immediately. This is not a professional solar-site assessment — it includes no shading analysis, roof survey, tilt and azimuth modelling, or interconnection review.
Enter electricity consumption in the calculator to get a suggested capacity.
Annual daily average of peak-sun-equivalent hours. Strongly site-, tilt- and shading-dependent.
Accounts for inverter, temperature, soiling and wiring losses.
Defaults to the factor for your region (DEFAULT). Unverified placeholder value.

Capacity vs. annual generation
Estimated annual energy yield (kWh) across system sizes, at the parameters above.
Equations used (all outputs are estimates)
Annual generation = capacity × sun hours/day × 365 × performance ratio = 5.0 × 4 × 365 × 0.8 = 5,840 kWh/yr
Avoided CO2e = generation × electricity emission factor = 5,840 × 0.4 = 2,336 kg CO2e/yr
- Sun hours, performance ratio and the emission factor are unverified placeholder assumptions unless you replace them with site-specific values.
- The model is annual and linear: it ignores seasonal and hourly output variation, shading, roof area limits, orientation, snow, soiling and degradation over time.
- Avoided emissions assume every generated kWh displaces grid electricity at the annual average factor — real displacement depends on when generation and demand coincide.
Estimated monthly energy generation
EstimateThe annual estimate spread across the year using the seasonal shape held in the configuration layer — an assumed profile, not measured site data.
Assumption: Illustrative seasonal shape for a mid-latitude northern-hemisphere site. Real profiles depend on latitude, tilt, weather and snow cover. Source: PLACEHOLDER — replace with cited published dataset.
Renewable Transition Score
An informal indicator we define ourselves, from 0 to 100, built only from your inputs and the modelled solar scenario. It is not an official environmental certification, rating or audit, and it cannot be compared with any external scheme.
